    same general area?

15
Volcanoes and Earthquakes Daily Double 400
  • Possible Answer Earthquakes happen where huge
    moving blocks (plates) of the earths surface are

  • Possible Answers
  • -cover your head
  • -stay away from windows
  • -sit under the table or against
  • an inside wall

22
Water and Wind 200
  • What natural force shaped this structure?

23
Water and Wind 200
  • Answer wind (or wind erosion)

24
Water and Wind 400 Daily Double
  • Explain how water might cause weathering.

25
Water and Wind 400 Daily Double
  • Answer Water gets into the cracks of rocks,
    freezes, expands and pushes on the side of the
    cracks until the rock breaks apart

26
Water and Wind 600

  • How can people cause erosion?

29
Water and Wind 800
  • Possible Answer
  • -When people build roads, houses, buildings, etc.
    they dig into the earth, which moves/shifts the
    land and causes erosion. In addition, it can
    cause rocks to fall, landslides, etc.
